BUSHING STRUCTURE.

Application filed July 21,

My invention relates to bushings and their supports found in such structures, for example, as barrels where the bushings serve to receive plugs or bungs which are screwed 6 thereinto. My invention has for its object the provision of improved means for obstructing rotation of the bushing when the bung is being turned.

In carrying out my invention, the sheet 10 metal member which carries'the bushing is formed with a circular rim portion angular to the body portion and surrounding a circular opening formed through said member, said body portion of said member being dished adjacent said rim portion to form a pocket having shoulders at its ends. The

' interiorly threaded bushing has a body portion surrounded by the rim portion of the aforesaid sheet metal member, a returned portion upon the exterior of and spaced apart from the body portion of the bushing,

said rim portion extending into the space between said body and returned bushing portions, said bushing having a second portion returned upon the first returned portion toward the connection of the latter and itself received, where connected with the-first returned bushing portion, in the aforesaid pocket and engaging. the aforesaid shoulders to obstruct turning movement of the bushing,

the unconnected rim of the bushing body portion desirably lapping the base of the rim portion of the aforesaid sheet metal member. In the preferred embodiment of the invention, the pocket in the sheet metal member surrounds the rim portion of this member, this pocket being outwardly bulged away from the side of the rim portion to widen the pocket at one portion thereof, shoulders being formed at the ends of the bulged portion of the pocket. The first aforesaid returned portion of the bushing, therefore, surrounds and is spaced apart from the body portion of the bushing and the aforesaid run portion of the sheet metal member carrying the bushing, this rim portion extending into space between this returned bushing portion and the body of the bushing.

The invention will be more fully explained in connection with the accompanying drawing in which Fig. 1 is one face view of a portion of a sheet metal member equipped in accordance with my invention; Fig. 2 is a side view of the structure shown in Fig. 1 as with the bushing and plug or hung in place;

Fig. 3 is a sectional view of the structure shown in Fig. 2, on a larger scale; Fig. 4 IS a view taken generally on line 4-4 of Fig. 2, on a larger scaleyFig. 5 is'a perspective view of the complete structure of my inso vention in its preferred embodiment; Fig. 6 is a perspective View similar 'to Fig. 2 with the bushing omitted; and Fig. 7 is a perspective view of the preferred form of bushing structure.

The sheet metal member 1, illustrated, may form a part of the structure which is to be supplied with a bushing, such as the end or other wall of a metallic barrel or container. This metal member is formed with m a generally circular rim portion 2 which is angular to the body portion of the sheet metal member and which rim portion surrounds a circular opening formed through said member. The body portion of said sheet metal member is dished around said rim portion to form a pocket 3. This pocket is outwardly bulged away from the side of the rim portion to widen the pocket at one portion thereof, as indicated at 4, so shoulders 5 being formed at the ends of the bulged portion 4 of the pocket. The bushing which is to be assembled with the sheet metal member 1 is'formed of metal and has an interiorly threaded body portion 6 surw rounded by the rim portion 2 of the sheet metal member. The bushing also has a returned portion 7 surrounding and spaced apart from the body portion of the bushing and also surrounding the aforesaid rim portion 2. The bushing is U-shaped in cross section at its returned portion and body portion, the rim portion 2 being-received in thespace between said body and returned bush- I ing portions, said returned bushing portion being received in the aforesaid pocket.

As illustrated, the returnedbushing portion 7 is a continuous ring which carries a second returned bushing portion 8 which is a segment of a ring. This bushing portion 8 is returned upon the bushing portion 7 toward the rim of the latter which is integrally connected with one rim of thethreaded body portion 6 of the bushing. The bushing portion 8 is received, where connected with the bushing portion 7, in thebulged portion 4 of the pocket that surrounds the rim 2 of the sheet metal member 1. The ends of the bushing portion 8 abut against the shoulders 5 at the ends of the pocket entie of the bushing is engaged with the end shoul--.

' ders 50f the pocket than would be resented for engagement with these shoul ers were this secondreturned bushing portion absent. To gain this same effect with no second returned bushing portion 8, the thickness, of the blank out of which the bushing is formed would have to be increased to an extent that is not permissible in die practice. The body portionof the bushing and the first and sec- 0nd returned portions thereof are annular and concentric with the rim portion 2 of the metal member.

sheet metal member 1, a construction which I have devised to enable the formation of the second returned bushing portion 8 by a die operation. The unconnected rim 10of the bushing body portion is outwardly curled to lap the base of the rim portion 2 whereby the sheet metal member 1 and said bushing are permanently assembled. The bun 9 may be rovided with a surrounding ange 11 whlch laps the bushing rim 10, the rim portion 2', and the contiguous portion of the sheet metal member 1 which'surrounds the rim portion 2. A sealing. gasket 12 may be interposed between the flange 11 and the contiguous portions'of the bushing and sheet The arcuate returned bushing portion 8 may be spaced as far apart from the returned bushing portion 7 as may be desired to afford any requisite resistance to the turning of the bushing, the bulging portion 4 of the pocket being corres ondingly widened.

Changes may be ma e without departing from the invention.

Having thus described my invention, I claim: 1.
